    Exclamation Galvolaser

    Hello Everyone

    I am studying on Galvolaser for my university finishing project. I find mirrors and f theta lens for 1060 nm but 1060 nm laser module is really expensive and ı never buy it. I can use 450 nm laser module but ı couldn't find the appropriate mirror and lens. So I have to prove can I use or can not use 450 nm laser with 1060 nm's mirrors product. How can I prove it ?

    ... dielectric coated mirrors for 1064nm are mostly transparent for 450/455nm - so better use silver coated mirrors.

    The f-theta lens for 1064nm will create much reflections inside, so you'll loose some power and receive some mirrored "satellite" spots - if you can't find f-theta for 445nm, then you can use 532nm types ... some satellite reflections too, but not this strong as with 1064nm lenses ...

    ... f-theta for 532nm or 455nm are not this common, so even more expensive than 1064nm ones

    Silver coated mirrors can be found cheap - search for the cheapish Chinese galvoscanners -- they mostly have silver-coated mirrors, which too are available as spare for repair ...
